About Oncimmune

Beating cancer, one test at a time

The battle against cancer hinges on early detection and then the delivery of effective treatment. Oncimmune is working to revolutionise both the detection of cancer and its treatment by harnessing the sophisticated disease detecting capabilities of the immune system to find cancer in its early stages. Our range of diagnostic tests assist clinicians to identify the presence of cancer four years or more before standard clinical diagnosis, whilst our technology platform and sample biobanks are helping healthcare companies to develop new cancer treatments.

Oncimmune was founded in 2002 and launched its platform technology in 2009, followed by its first commercial tests, EarlyCDT Lung and EarlyCDT Liver. To date, over 158,000 tests have been performed for patients worldwide. EarlyCDT Lung was also used in what is believed to be the largest randomised controlled trial for the early detection of lung cancer using biomarkers, the successful National Health Service (NHS) ECLS trial of 12,209 high-risk smokers in Scotland which demonstrated EarlyCDT Lung reduced the incidence of patients with late-stage lung cancer or unclassified presentation at diagnosis, compared to standard clinical practice.

Oncimmune, headquartered at its laboratory facility in Nottingham, UK, has a discovery research centre in Dortmund, Germany and in London, UK and a partner representative office in Shanghai, China. Oncimmune joined the Alternative Investment Market (AIM) of the London Stock Exchange in May 2016 under the ticker ONC.L.

What is EarlyCDT Lung?

A blood test using a panel of seven immunogenic proteins for the testing of tumour-related antibodies specific to lung cancer.
